World of Warcraft Updated Preview

GameSpot has put together an updated preview of World of Warcraft, based upon their experience with the game's third phase of beta and introduction of PvP. Check it out:
As you might expect from an early test version of a game that is months away from release, player-versus-player battles aren't anywhere near being perfectly balanced right now. We've seen numerous lopsided encounters where large groups of players have ganged up on individuals, and even a few areas in which high-level players have crept into areas where new characters of enemy races begin their adventures. While these high-level assassins (some players might refer to these high-level sneaks by creatively removing a few letters from the word "assassins") can't actually attack low-level characters unless they themselves consent to PvP first, we've seen instances where players have done abusive things, like kill off important trainers or quest-givers, which leaves some low-level players out of luck until these key NPCs respawn. Amusingly, Blizzard has implemented protection against this sort of activity whereby important NPCs will spawn high-level guards when they come under attack.
